Charles-Marie Widor’s ten organ symphonies sit at the heart of his extensive oeuvre. They reveal Widor’s mastery of the form with their profundity, technical difficulty and sonorous colour. Symphony No. 7, Op. 42, No. 3 inaugurated a new, orchestral approach to the genre and encompasses dreamlike sonorities, Chopinesque melancholy and majestic bravura. The Symphonie gothique, Op. 70 makes explicit reference to Gregorian chant, developing a kind of theological ‘programme music’ that is both austere and consolatory.
